tshirt factory for Scalable Private-Label Apparel

Full-Package OEM

A full-package OEM handles development, fabric sourcing, patterns, grading, sampling, cut-and-sew, decoration, packing, and export coordination. At 100 units per style and color, this model suits brands with a tech pack, sketch, or reference garment. It trades a higher unit cost for fewer supplier handoffs and faster problem-solving.

ODM And Private Label

ODM programs start with factory-ready silhouettes that buyers adapt through fabric, color, labels, and artwork. A private-label order usually moves faster than a ground-up pattern, but offers less exclusive design control. Ask: can an existing block deliver my target look without costly revisions?

CMT And Specialists

CMT factories cut, make, and trim against buyer-supplied patterns and materials; the buyer controls sourcing and specifications. Specialist print factories focus on screen print, DTG, DTF, or transfers rather than garment engineering. Ask: do we have the technical team and material control to manage separate vendors?

Scale-Focused Producers

Vertically integrated producers combine key steps such as knitting, dyeing, cutting, and sewing, improving lead-time control when capacity is available. Large-volume basic manufacturers optimize repeatable blank tees and high runs, often requiring larger MOQs. Ask: is low landed cost more important than flexibility, fit development, and small replenishments?

Fiber Choices And Positioning

100% ring-spun combed cotton gives a smoother, softer surface than open-end cotton and suits elevated basics. Pima cotton raises fiber-length expectations, while organic cotton needs documented chain-of-custody claims. Recycled polyester lowers virgin-fiber dependence and adds durability, but can feel less natural against skin. Viscose or modal improves drape; 3–8% elastane improves recovery for fitted silhouettes.

• Ring-spun: soft premium jersey
• Open-end: economical, structured hand
• Organic: verify GOTS scope certificate
• Recycled blends: request fiber-content evidence

Knit, Weight, And End Use

Single jersey is the standard T-shirt knit, while interlock creates a denser, cleaner two-sided face. Rib knit belongs mainly at neckbands because its elasticity helps the collar recover after wear.

Wash Tests And Compliance

3–5% residual shrinkage after the agreed wash method is a common acceptance target, but the approved specification controls. Test colorfastness to washing, rubbing, and perspiration before bulk approval. OEKO-TEX Standard 100 addresses harmful-substance testing, while GOTS covers defined organic-textile processing requirements. Request current certificates from the relevant mill rather than relying on a fabric label.

Fit And Product Options

XS–3XL programs need graded shoulder, chest, body-length, and sleeve increments; simply enlarging one pattern distorts oversized and extended-size fits. 180–260 GSM jerseys can be specified with crew, ribbed mock, V, or polo necklines; choose dropped, raglan, cap, or long sleeves. Pantone dyeing, garment dye, acid wash, and enzyme softening should be approved on the actual fabric.

Branding Components

Neck prints remove a sewn main label, but wash-care labels remain necessary for fiber and care information in destination markets. Woven labels, size tabs, hangtags, custom bags, tissue, and cartons should be finalized with artwork, placement, and barcode requirements before bulk packing.

Decoration Method Matching

Screen printing suits repeat artwork and scalable runs, while DTG is practical for detailed short runs on cotton-rich garments. Request strike-offs for dark-fabric opacity, stretch, hand feel, and wash testing. Embroidery and appliqué add texture but need stabilizer and placement review; dense designs can pucker lightweight jersey.

Stitches And Seams

8–12 stitches per inch is a practical target for most jersey seams; specify the count by seam, not merely ‘strong stitching.’ 4-thread overlock side seams, coverstitch hems, and reinforced shoulder seams reduce popping and distortion through wash cycles.

• Specify SPI by seam location
• Call out overlock and coverstitch
• Require clean thread trimming

Collar And Fabric Stability

1:1 rib collars should recover after stretch testing and sit flat after laundering; define rib composition, finished width, and neck opening measurement. 3–5% residual shrinkage is a common approval ceiling when measured by the agreed wash method. Require pre-shrinking where needed, control fabric skew, and approve wash/softening finishes against a retained sample.

• Add shoulder tape width and material
• Test collar recovery after washing
• Record lengthwise and crosswise shrinkage

Tech Pack And Final Approval

±1 cm tolerances on key adult tee points can be appropriate, but neck width, body length, and chest must be listed point by point with grading rules. AQL 2.5 final inspection should define the acceptable defect threshold, inspection level, measurement method, wash standard, and sealed golden sample. JUNSHEEN can retain approved patterns, graded sets, and material records for repeat-order consistency.

• Attach annotated measurement spec
• Approve pre-production sample
• Set AQL, defect definitions, and carton checks

Verify Category Capability

100-unit minimums suit capsule launches, but confirm the MOQ applies per style, color, fabric, and size breakdown. Ask for recent comparable jersey programs, factory-floor photos, and a current capacity plan. 200-plus workers or a stated monthly capacity matters only when supported by line allocation, production calendars, and subcontracting disclosure. Confirm who cuts, sews, decorates, and packs the garment.

• Request comparable product references
• Confirm MOQ by color and fabric
• Ask whether any process is subcontracted

Approve Samples And Materials

1 sealed approval sample should define measurements, tolerances, stitch density, print placement, shade, labels, and packing. Measure it after wash testing; compare shrinkage, torque, pilling, and print cracking against the specification. Pantone references and fabric swatches should accompany the sample when color or hand feel is critical. Request fiber content, GSM, finished width, mill details, and available OEKO-TEX or GOTS documentation where applicable.

• Review graded measurement chart
• Retain approved trim card
• Document wash-test results

Check Commercial Reliability

3 documents reduce avoidable risk: business registration, export references, and a written quotation stating Incoterms, lead time, payment milestones, and defect handling. Ask for destination-market experience and whether the factory can prepare commercial invoices, packing lists, and origin documentation. 30/70 or other deposit structures should be tied to sample approval and pre-shipment inspection, with the balance settled before shipment. Obtain a pro forma invoice listing bank beneficiary details, quantities, unit prices, and the approved specification revision.

• Verify legal entity and bank account
• Define inspection and rework process
• Confirm shipping document responsibility

Price-Only Supplier Selection

A quote that is 10% lower can omit fabric weight, shrinkage allowance, inspection scope, or packaging. The consequence is a higher landed cost after claims and remakes; compare like-for-like quotations against a signed specification sheet.

• Match GSM, fiber content, decoration, packing, and Incoterms
• Request sample and bulk-quality inspection points
• Compare landed cost, not unit price alone

Uncontrolled Product Specifications

A sketch without Pantone references, measurement tolerances, stitch details, or label placement invites interpretation. The control is a production-ready tech pack plus approved fabric swatch, artwork proof, fit sample, and graded size set before bulk cutting.

• Specify tolerance for key measurements
• Approve color, hand feel, and wash result
• Test screen-print or transfer artwork on fabric

MOQ And Lead-Time Blind Spots

A 100-unit minimum may apply per style and color, not across five colors combined. Splitting quantities can raise cost or block production; confirm MOQ, color allocation, fabric availability, and trim lead times before launching.

• Reserve custom labels and zipper lead time
• Confirm stock versus custom-dyed fabric
• Set a realistic critical-path calendar

Weak Delivery And Payment Controls

A promised ship date without an approved sample date, material arrival date, and inspection window is not a production schedule. Use milestone dates, written acceptance criteria, and staged payment terms; do not release the final balance until agreed pre-shipment checks are complete.

• Document deposits, balances, and shipment release
• Define rework responsibility for failed inspections
• Keep approvals and change orders in writing

Define The Product Brief

Week 1 should identify the wearer, occasion, fit direction, competitors, and retail price. The decision gate is a one-page brief: if the product cannot be described clearly, do not request samples. Two colorways reduce inventory risk while preserving a recognizable launch identity. Specify oversized or regular fit, intended GSM, logo placement, Pantone references, and required labels.

Build And Test Samples

One complete tech pack should show measurements, graded size chart, construction, artwork, trims, and packaging. A tshirt factory can then assess manufacturability from a tech pack, sketch, reference garment, or mood board. One prototype is the decision gate for fabric hand, shrinkage, print quality, and fit. Revise measurable issues first, then approve a size set from XS through 3XL before bulk cutting.

Approve Production And Replenishment

100 units per style and color is a practical capsule threshold for testing demand without eliminating differentiation. Approve a pre-production sample only after measurements, artwork, wash results, and labeling match the signed specification. Three inspection stages—fabric receipt, in-line sewing, and packed-goods review—catch defects before shipment. Book freight after carton dimensions and destination are confirmed, then retain sell-through data, patterns, and material records for replenishment.
